A medical assist device relocates patients from a first support such as a bed to a second support such as a chair or wheelchair. Upon location of the assist device to a position adjacent such first support, the patient may stand on a rotatable platform of the assist device. Upon actuation of the motor, preferably by a remote controller, the platform is caused to slowly rotate through a desired angular path to position the patient adjacent the second support. A steadying structure is provided for gripping by the patient. Under one embodiment, the steadying structure is designed to be collapsible.
